Just another Simple static analysis tool to find bugs like a grep unix command, at mosca have a modules, that was call egg, each egg is a simple config to find bug at especific language like PHP,Ruby,ASP etc... Example of egg config at directory "egg", If Mosca read a line with vunerability of egg in source code, then, mosca have alert about vulnerability and save at logs. *why static ? because is not dynamic... uses static code to search... don't confuse with academic views hahaha this program use simple regex with PCRE... https://github.com/CoolerVoid/Mosca
